text: A particularly stable derivative is di-t-butylsulfurdiimide.  It is prepared by reaction of tert-butylamine with sulfur dichloride to give the intermediate "S(N-t-Bu)", which decomposes at 60 °C to give the diimide.  A second route to sulfur diimides involve treatment of sulfur tetrafluoride with amines.  A third route involves transimidation of disulfonylsulfodiimide:
  :S(NSOPh)  +  2 RNH  →   S(NR)  +  2 PhSONH
  N,N'-Bis(methoxycarbonyl)sulfur diimide (MeOC-N=S=N-COMe) is obtained from methyl carbamate.
